Background: The impact of cognitive status on outcomes of patients with atrial fibrillation (AF) is not well defined.
Aims: To assess the prevalence of cognitive impairment in AF patients and evaluate its association with: i) all-cause mortality; ii) a composite endpoint of death, stroke/systemic embolism, hemorrhages, acute coronary syndrome, pulmonary embolism, new/worsening heart failure.
Methods: In a cohort study, cognitive status was assessed at baseline by the Mini Mental State examination adjusted for age and education (aMMSE).
Prescription of non-vitamin K antagonist oral anticoagulants (NOACs) requires an assessment of renal function (RF) and the Cockcroft-Gault (CG) equation is traditionally recommended. The objective of the study was to evaluate the potential changes in NOACs management using different equations for estimating RF. In a post hoc analysis of a prospective cohort of patients with atrial fibrillation, we considered different equations: (1) CG for creatinine clearance (CrCl), (2) modification of diet in renal disease (MDRD), (3) CKD-EPI, (4) Berlin Initiative Study 1 (BIS-1) and (5) full age spectrum (FAS), for glomerular filtration rate (GFR).
